Wiggins going back to track

Bradley Wiggins is turning his back on "cut-throat" road racing and has ruled out competing in any more grand tours, the 2012 Tour de France champion said on Thursday.

Wiggins, who won a silver medal in team pursuit at the Commonwealth Games on Thursday, will instead focus on the track where he hopes to compete at the Rio de Janeiro Olympics in 2016.

"I've kind of done the road now. I've bled it dry," the 34-year-old told the BBC.
